How would I go about solving this problem? Please list steps, thank you!

50 grams of the solid X at its melting point of 4 Degrees C are put into 200 grams of liquid X (Cp=1.5 j/g C) at 25 Degrees C. The final temperature of the mixture is 8 Degrees C. What is the hear of fusion for X?

[Vidya]

This is based on the heat lost by liquid X is equal to heat gained by the solid X
Heat lost by liquid X= m c (change in temperature)
here change in t = 25-8
Heat gained = heat of fusion + mc(change in temperature )
here change in t = 8-4
you can work on this concept and try to get the answer
